Public Library CONNECT is an OverDrive "program" that is a cooperative arrangement between schools and local public libraries that allow the schools to use their school logins to access the public library OverDrive collection and then read public library titles on the Sora platform.
Public Library CONNECT is free of charge, but schools must be set up on the Sora platform first (either the free platform, via Commonwealth eBook Collections, or as a standalone account) and the public library has to agree to the arrangement.
